Question

In natural numbers, $x–5=-5$ has _______ solution.

Answer 1

Solve the given equation:

The given equation can be simplified as,

$x–5=-5$

$\Rightarrow$ $x=-5+5$

$\Rightarrow$ $x=0$

But, as we know, the set of natural numbers $\mathrm{\mathbb{N}}=\left\{1,2,3,4,5,...\right\}$

So, it is clear that $0\notin \mathrm{\mathbb{N}}$

Hence, there is no solution of $x–5=-5$ in natural numbers.
